INLINE DILUTION OF MICROFIBRILLATED CELLULOSE

The present invention relates a process and a system for the point-of-use dilution of microfibrillated cellulose (MFC) from a higher solids content to a lower solids content， for example from a solids content in the range of 5% weight by weight (“w/w”)-50% w/w， preferably 5% w/w-30% w/w， further preferably 5% w/w-15% w/w， down to a solids content of below 7% w/w， preferably below 5% w/w， preferably to a solids content of 0.01% w/w-5% w/w， further preferably to a solids content of 0.1% w/w-3% w/w. The process at least comprises the following steps: (i) providing microfibrillated cellulose in a solvent， wherein the solids content is in the range of 5% weight by weight (“w/w”)-50% w/w， preferably 5% w/w-30% w/w， further preferably 5 w/w-15% w/w; (ii) subjecting said microfibrillated cellulose from step (i) to a dilution step in a rotor-stator mixer; (iii) simultaneously to step (ii): injecting solvent into the rotor-stator mixer， or into a volume segment upstream of the rotor-stator mixer， in order to lower the solids content of the microfibrillated cellulose in the rotor-stator mixer.
